It's actually a sure enough 1/2 ton pickup rearend with the existing pads on top. It's out of a 68 model truck, so I will probably swap the big drum brakes that I have laying around from a C body onto it before I bolt it in. If the center register on the existing 9 1/4 ends up being the same as the axles in the 8 3/4, I may just swap those brakes over and redrill the drums to 4.5.
